To further my atemps to diagnos this issue. I pulled the pcm fuse. the car still is not cured and the problem was there imediately. So that tells me it is mechanical and not "learned" When I try to rev the engine in neutral it stumbles till about 3000rpm then goes about its business as per usual. You can really hear it through the intake when it is stumbleing. Gonna clean the maf this weekend and the UIM but I'd be surprised if that cleared this up. Anymore sugestions?
